The GTX 770 is a 230W card when maxed out. That will draw ~19.2 amps from the +12V rail(s). MB's are usually another 30W, CPUs vary, fans, etc are miniscule. Nvidia recommends a 600W PSU for that card.

You won't go wrong with the 650W Seasonic.

Seasonic 650W bronze, I've never heard of the "SuperFlower 550W Gold"

Yes, that's not a Seasonic. But Jonny Guru gives it a good review and is well satisfied with the Superflower 550W Gold.

If your current 550 Watt power supply unit has a combined +12 Volt continuous current rating of 34 Amps or greater and has at least one 6-pin and one 8-pin PCI Express supplementary power connectors it will be sufficient.
